I'M HAVE BEEN EXPERIENCING SEVERAL TECHNICAL ISSUES WITH MY 2002 AVALANCHE THROUGH YEARS. I CAN REMOVED MY KEY WHEN MY IGNITION TURNED ON TO DRIVE. MY TRUCK ALSO REDUCES ENGINE SPEED WHEN DRIVING AT 45 MPG. IT RESULT FOR ME TO PULL OVER ON THE INTERSTATE TO RESET THE PCM TO DRIVE. THEN MY CHECK ENGINE LIGHT WILL APPEAR ON ALSO. THEN IT WILL CLEAR ITSELF SOMETIMES. SANDY SANSON A GM DEALERSHIP IN PENSACOLA FL WHERE I BOUGHT THE CAR IN 2006 HAS CHARGE ME UNNECESSARY FOR PARTS AND LABOR TO FIX THESE ISSUES. WHEN BRINGING THE PROBLEM TO THE ATTENTION OF AUTO REPAIR. A SALE REP SAID MY KEYCHAIN CAN WHERE MY IGNITION OUT. HE ALSO STATED THAT MY CAR NEEDED OTHER COMPONENT PARTS IN ORDER TO FIX THE PROBLEM. WHICH NEVER SOLVE THE MAIN ISSUE THAT I REQUESTED TO BE FIX. I ALSO TALK TO THE HEAD SUPERVISOR AND GOT POOR CUSTOMER SERVICE. FURTHERMORE, IT HAS NOT BEEN RESOLVE AT THIS MOMENT. I CONTINUE TO DRIVE BECAUSE MY TRUCK IS THE ONLY TRANSPORTATION I HAVE AT THE MOMENT. I'M GOING TO SPEAK TO THE DEALERSHIP AGAIN ABOUT THIS ISSUES, BUT PLEASE ASSIST ME BECAUSE I BEEN HAVING THE SAME PROBLEMS. THAT ARE IN THE HEADLINE AT THIS MOMENT. I WRITTEN ABOUT MY REDUCE ENGINE SPEED IN THE PAST. *TR

I WAS DRIVING HOME AROUND 9:30 PM. AS I WAS GOING DOWN A HILL I STEPPED ON MY BRAKES AND THE PEDAL WENT TO THE FLOOR. NO BRAKES AT ALL, NO SAFTEY FEATURES KICKED IN, NO WARNING LIGHTS. JUST A CATASTROPHIC BRAKE FAILURE. LUCKILY FOR ME IT WAS A SMALL HILL AND I WAS ABLE TO STOP BY GOING INTO LOW GEAR AND USING THE EMERGENCY BRAKE. I TURNS OUT THAT THE BRAKELINES FROM THE MASTER CYLINDER TO THE ABS CONTROL BOX WERE ROTTED AND FINALLY GAVE OUT. THIS IS A 2002 TRUCK WITH 62,000 MILES ON IT. I KNOW FROM PREVIOUS EXPERIENCE WITH OLDER CARS THAT IF A BRAKE LINE FAILS, THERE IS A VALVE THAT IS SUPPOSED TO CUT OFF THE OPEN LINE SO THERE IS SOME BRAKES LEFT. I REPEAT, NO SAFTEY FEATURES WORKED, NO WARNING LIGHTS, NO VALVE KICKING IN,NOTHING. THIS IS A KNOWN ISSUE WITH GM. A QUICK SEARCH ON THE WEB BROUGHT UP THOUSANDS OF HITS ON THIS PROBLEM. JUST 20 MINUTES EARLIER I WAS ON THE NYS THRUWAY DOING 65 MPH. IF I LOST BRAKES AT THAT SPEED AND WITH THE OTHER TRAFFIC, THERE MOST CERTAINLY WOOD HAVE BEEN A CRASH AND POSSIBLE LOSS OF LIFE.

The Office of Defects Investigation (ODI) received Defect Petition DP10-003 on March 2, 2010, requesting the investigation of model year (MY) 2003 Chevrolet Silverado 2500HD 4WD pickup trucks for corrosion failures of the vehicle brake lines.DP10-003 was granted and on March 30, 2010, Preliminary Evaluation PE10-010 was opened on more than six million model year 1999 through 2003 light trucks and sport utility vehicles manufactured and sold by General Motors Corporation (GM).On July 2, 2010, ODI received GM's response to an information request, which included GM's assessment of the frequency and safety consequences of the alleged defect. GM stated that:(1) the brake system of the subject vehicles is split front/rear and should a brake pipe suddenly fail for any reason, the affected vehicle would be capable of stopping with the pressure supplied by the remaining circuit; (2) the subject vehicles were designed to meet the hydraulic circuit partial failure requirements of Federal Motor Vehicle Safety Standards 105 and 135, Light Vehicle Brake Systems; and (3) should a brake fluid leak occur for any reason, the brake system malfunction indicator lamp (MIL) would illuminate and warn the driver before the brake fluid level was low enough to cause a loss of line pressure.ODI's and GM's analysis indicates that 85 percent of the complaints occurred on vehicles used primarily in States that use salt on the roads during Winter months (Connecticut, Delaware, District of Columbia, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia and Wisconsin).Overall the complaint rates per 100,000 vehicles for Salt Belt States is 43.0 and Non-Salt Belt is 3.0.In approximately 25 percent of the complaints the brake pipe failure occurred suddenly, with no warning (i.e., no MIL, Brake Fluid Loss Warning), and resulted in extended stopping distances.In 30 of these the increase in stopping distance that resulted was a factor in the crash and in 10 others the vehicle was intentionally steered off the road or into another lane of travel in order to avoid a crash.This investigation has been upgraded to an Engineering Analysis (EA11-001) for subject vehicles sold or currently registered in Salt Belt States to further assess the scope, frequency and safety risks associated with sudden failures of corroded brake pipes that can result in decreased brake effectiveness. ODI will continue to gather information on subject vehicles outside the Salt Belt as well.

Opened Aug 1, 2002 · Closed Jan 12, 2004
Status: closed (inferred from source dates) · Vehicle Speed Control:linkages
THIS INVESTIGATION INVOLVES THE GENERAL MOTORS CORPORATION (GM)THROTTLE BODY (TB) UTILIZED IN MODEL YEAR (MY) 1999-2002 SILVERADO, SIERRA, TAHOE, SUBURBAN, AVALANCHE AND YUKON (SUBJECT VEHICLE(S)) WITH 4.8L, 5.3L, AND 6.0L ENGINES. THE TB VALVE MAY INTERMITTENTLY STICK IN A CLOSED POSITION.IN SUCH A SITUATION, AN OPERATOR MAY APPLY ADDITIONAL ACCELERATOR PEDAL FORCE TO INCREASE ENGINE SPEED.THE APPLICATION OF ADDITIONAL ACCELERATOR PEDAL FORCE, TO OPEN A STUCK THROTTLE VALVE, MAY OPEN THE THROTTLE VALVE MORE THAN INTENDED AND, IN TURN, ACCELERATE THE ENGINE AND VEHICLE MORE THAN INTENDED AND REASONABLY EXPECTED BY THE DRIVER.ON AUGUST 1, 2002, THE OFFICE OF DEFECTS INVESTIGATION (ODI), OF THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION (NHTSA), OPENED THIS ENGINEERING ANALYSIS.THE INVESTIGATION REVEALED THAT TWO FACTORS MAY CAUSE THE DEFECT: 1) TB MANUFACTURING PROCESS PROBLEMS; AND 2) ACCUMULATION OF DEPOSITS (A PCV SYSTEM BY-PRODUCT) ON OR AROUND THE TB THROTTLE VALVE AND BORE.ODI CONCLUDES THAT THE TB PERFORMS IN A DEFECTIVE MANNER AFTER ANALYZING GM?S DATA SUBMISSIONS, AND TEST DATA COLLECTED BY THE VEHICLE RESEARCH AND TEST CENTER (VRTC).FIFTY-NINE CRASHES ARE ALLEGED TO HAVE OCCURRED AS A RESULT OF GM?S TB DEFECT.THE MAJORITY OF THE CRASHES INVOLVE A SINGLE VEHICLE, ENGAGING IN A CLOSE QUARTER VEHICLE MANEUVER (OR LOW SPEED), AND CAUSING ONLY MINOR PROPERTY DAMAGE.FOUR OUT OF THE FIFTY-NINE CRASHES INVOLVE INJURY, AND THOSE INJURIES WERE MINOR.ALTHOUGH GM?S TB IS DEFECTIVE, BASED ON THE EVIDENCE GATHERED, ODI HAS FOUND THAT THE ACCELERATOR PEDAL FORCE REQUIRED TO OPEN A STUCK THROTTLE VALVE IS NEGLIGIBLE, AND THE THROTTLE VALVE DOES NOT STICK IN THE OPEN POSITION.THEREFORE THIS ENGINEERING ANALYSIS (EA02-015) WILL BE CLOSED AT THIS TIME.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST.FOR A DETAILED DISCUSSION OF THE TB COMPONENT AND TESTING, PLEASE SEE THE ATTACHED REPORT.
